The instamatic line of cameras were cheap and took 126 or 110 film - they sold tens of millions in the 60s and 70s. This one took 126 film and was released in 1965. It differed from the 100 model in that it took the new flash cubes instead of single flashbulbs - 4 shots instead of one!
you can find these instamatics everywhere - this one cost me 90 cents.
